Hi I am new to this forum and I believe I found the answer to your question
since I had the same problem. A key in your registry is probably pointing to
a deleted file refered to as desktop.html
If you go into your regedit and follow this path: HKEY_CURRENT
USER/SOFTWARE/MICROSOFT/WINDOWS/CURRENTVERSION/POLICIES/SYSTEM
In there you may see a key that points to the C:\Windows\Web\desktop.html
If you see that key DELETE IT. Your virus software probably found this
hijack desktop viruz and deleted the infected file already.
This took me 2 days to figure out and it was this forum that helped me
figure it out. THANKS and I hope this helps!
